Description

An automated device for simultaneous retraction of the liver and stomach during laparoscopic pancreatic surgery

Technical field

Background technique

The human pancreas is located deep below the liver and behind the stomach, and is a retroperitoneal organ. Pancreatic surgery has always been considered a restricted area of surgery due to its deep location, difficulty in exposure, and proximity to major blood vessels and important organs. Due to the special characteristics of pancreatic tissue, the incidence of postoperative complications is high and serious, and improper treatment can be life-threatening. Over the past 20 years, with the popularization of minimally invasive concepts and the development of laparoscopic technology, more and more benign and malignant pancreatic tumors have been treated laparoscopically or robotically. Due to the difficulty of the operation, most laparoscopic pancreatic surgeries are only performed in larger medical centers.

The pancreas is located deep, and during laparoscopic pancreatic surgery, it is often necessary to retract the liver and stomach to expose the pancreas to facilitate surgical operation. However, the currently used traction methods are often time-consuming and labor-intensive, can easily cause side damage to the liver, and have poor traction effects, resulting in poor exposure of the surgical field, often resulting in unsmooth surgical procedures. Some surgeries may cause intraoperative complications due to the inability to accurately expose the liver. Transfer to laparotomy. By well retracting the liver and stomach, the pancreas is fully exposed, so that the surgeon's hands can be freed so that he can focus on precise tumor resection and subsequent reconstruction. Therefore, there is a lack of a device on the market that can be used to simultaneously retract the liver and stomach during laparoscopic pancreatic surgery to facilitate exposure of the surgical field.
